Last Crew of Space Shuttle Discovery Practices Launch Escape

The last crew of the space shuttle Discovery staged a full
dress rehearsal today (Oct. 15) for the spacecraft's final voyage, capping the
launch practice with an emergency escape drill NASA hopes never to use.

The six astronauts slated to launch on Discovery's final
mission Nov. 1 arrived at NASA's Kennedy Space Center (KSC) in Cape Canaveral,
Fla., earlier this week to participate in training exercises, known as the
Terminal Countdown Demonstration Test. ?

Space Station in just over two weeks for an 11-day construction flight. [Photos:

"The vehicle is looking great, all of our activities
are going great," shuttle commander Steve Lindsey told reporters yesterday
(Oct. 14) from the Launch Pad 39A at KSC. "We are basically trained and
ready to fly. Just a few more weeks of activities we have to go through, and
then we'll hopefully be back here for an on-time launch on Nov. 1."

While at KSC, the astronauts checked the fit of their orange
spacesuits, reviewed firefighting methods, familiarized themselves with the
flight hardware, and examined the cargo that will be hauled to the space
station in Discovery's payload bay.

The crewmembers also received training on how to escape into
the launch pad's slidewire baskets and armored M-113 personnel carriers in the
event of an emergency pad escape.

The exercises are intended to familiarize the crew with the various
safety equipment and procedures that, if necessary, may need to be put into
action on the day of launch.

On its final spaceflight, space
shuttle Discovery will take critical spare parts to the station, including
a storage room and a humanoid robot helper to assist the crew of the orbiting
outpost.

Shuttle era's end looms

But, even with the excitement surrounding the upcoming
mission, Lindsey calls the preparations for Discovery's final flight a
bittersweet experience.

"For me personally, this will be my third flight on
Discovery," Lindsey said. "Discovery is a workhorse ? fleet leader in
number of flights. It's a great machine, a great vehicle. As far as the last
flight, it's a privilege for us to be able to fly it on the last flight. It's a
real tribute to the folks here and at the other manned spacecraft centers for
all they've done to keep these vehicles flying and being able to do all the
things they do."

NASA will retire the three remaining shuttles in its fleet ?
Discovery, Atlantis and Endeavour ? next year to make way for a new plan aimed
at sending astronauts to visit an asteroid and Mars. Discovery is the oldest of
NASA's space shuttles.

On Monday (Oct. 11), President Barack Obama signed a major
NASA act that turns his vision for U.S. space exploration into law. The NASA
authorization act scraps the space agency's previous moon-oriented goal and
paves the way for a manned mission to an asteroid by 2025. A manned mission to
Mars is envisioned for some time in the 2030s.

The bill also calls for a budget of $19 billion for NASA in
2011, adding one extra space shuttle flight before the fleet retires next year,
and the extension of the International Space Station through at least 2020.

Still, the legacy of Discovery will be celebrated by the STS-133
crew during their upcoming mission, and after the orbiters are retired, the
public will also be able to share in the illustrious history of the space
shuttle program.

"Our ship Discovery was named after several predecessor
ships, also named Discovery ? all ships of exploration," Barratt said.
"It's a culmination of a great heritage. And we hope there are future
ships bearing that name. We will be carrying a medallion from the Royal Society
that was struck in honor of Captain Cook. On Cook's third voyage, there was a
ship called Discovery, and that's the main ship for which our ship Discovery
took its name."
